Book Description
This issue of ZooKeys celebrates the 75th birthday of Alexandr P. Rasnitsyn, a pioneer in the palaeontology and phylogeny of Hymenoptera, as well as a leader generally in insect systematics and evolution. Born in Moscow, Russia, on 24 September 1936, he developed his passion for Hymenoptera at an early age. After completing his degrees in 1960 he joined the Arthropoda Laboratory in the Paleontological Institute of the USSR (now Russian) Academy of Sciences, Moscow, and worked his way from Technician to the Head of the laboratory, in this capacityÿ leading the most productive group of paleoentomologists for 28 years. He has co-authored and edited several keystone books on insect paleontology and evolution, including History of Insects (2002), the first large-scale work of its kind in English. Rasnitsyn served as the first President of the International Palaeoentomological Society, and was bestowed Honorary Membership by the Russian Entomological Society and in 2008 with the Distinguished Research Medal of the International Society of Hymenopterists. Herein colleagues from around the world have presented original contributions to the systematics of diverse insect orders, living and fossil, as a tribute to this pioneer of Hymenoptera and paleoentomological research. Numerous new taxa are described and their phylogenetic implications explored. A biographical sketch and a list of Rasnitsyn?s more than 360 scientific publications (spanning 52 years) are provided.

Book Description
The geological and palaeontological records of climate change and evolutionary events reflect Earth’s widely fluctuating climate systems. Past climates hold the clues to understanding future developments. In this context, research on linked climate, biodiversity and sea-level fluctuations of the Devonian contributes to the general knowledge of deep-time climate dynamics. A fruitful co-operation between the International Geoscience Programme IGCP 596 and the International Subcommission on Devonian Stratigraphy (SDS) addressed the complex succession of climate-linked Devonian global events of varying magnitude. The primary goal of IGCP 596 was to assess mid-Palaeozoic climate changes and their impact on marine and terrestrial biodiversity using an interdisciplinary approach. The focus of SDS includes a revision of the eustatic sea-level curve and the integration of refined chrono- and biostratigraphy with modern chemo-, magneto-, cyclo-, event- and sequence stratigraphy. This enabled the much improved dating and correlation of abiotic perturbations, evolutionary changes, organism and ecosystem ranges. Results by 37 authors are presented in 14 chapters, which cover the entire Devonian.

Book Description
This book provides practical morphological information, together with detailed illustrations and brief explanatory texts. Each chapter starts with a brief introduction, and goes on to describe the respective organism’s morphology in detail through numerous illustrations. This is followed by a brief note on its classification, and concludes with illustrated examples of stratigraphically important organisms through time with their major distinguishing characteristics. Featuring over 2500 clearly labelled, hand-drawn and classroom-friendly illustrations, the book offers a fundamental resource for budding palaeontologists, petroleum geologists and palaeobiologists.

Book Description
Towards the Balance and Management of the Carbon Budget of the Biosphere The current state of misunderstanding of the global C cycle and our failure to resolve an issue that has been debated for 100 years (Jones and Henderson-Sellers, 1990) speaks loudly about the limitations of modem science when faced with the complexity of the biosphere. Efforts to understand and balance the global C budget have gone through several phases. First was a holistic view of the C budget as part of efforts to understand the geochemistry of the Earth (e. g. , Clarke, 1908). Next, came a period of data collection and sythesis which focused on the diversity of sectors of the biosphere. This phase culminated in the early 1970's with the realization that humans were greatly impacting the global C cycle as measured at the Mauna Loa Observatory (Keeling et al. , 1973). New syntheses of the global C budget emerged at this time (Woodwell and Pacan, 1973; Bolin et al. , 1979). The next phase was one of controversy and intense focus on particular sectors of the biosphere. The controversy rested on discrepancies about the role of the terrestrial biota in the global C cycle and the failure to account for sufficient C sinks to absorb all the C emitted by land-use change in the tropics (Woodwell et al. , 1978, 1983; Houghton et al. , 1983).

Book Description
The Ordovician was one of the longest of the geological periods, characterized by major magmatic and tectonic activity, an immense biodiversification, swings in climate and sea levels and the first Phanerozoic mass extinction. ‘A Global Synthesis of the Ordovician System’ is presented in two volumes in The Geological Society, Special Publications. This first volume (SP532) charts the history of the Ordovician System and explores significant advances in our understanding of its biostratigraphy, including more precise calibration of its timescale with tephra chronology and regional alignments using astrochronology and cyclostratigraphy. Changes in the world’s oceans, their shifting currents and sea levels, the biogeography of their biotas and the ambient climate are described and discussed against a background of changing palaeogeography. This first volume also includes syntheses of the Ordovician geology for most European countries, including historical key areas, such as Great Britain, Baltoscandia and Bohemia. The second volume (SP533) provides synthetic aspects of the Ordovician geology of most other parts of the world.

Book Description
stable isotope ratios act as naturally-occurring tracers for organic matter, making possible, under certain conditions, the quantification of coastal-offshore exchanges. In general, organic matter has isotope ratios characteristic of its origin (e. g. plants with different modes of photosynthesis and different growth conditions, anthropogenic compounds). These ratios are maintained as the organic matter moves through the biosphere and geosphere. A mixture of organic matter from two sources has isotope ratios intermediate between those of the two sources, in proportion to the fraction of material from each source. Isotope ratios are one of the few methods which can trace organic matter as it moves through natural ecosystems. Ratios can be measured on both the total organic matter and on particular chemical fractions or compounds. When used on organisms, isotope ratios provide information of organic matter actually assimilated into body tissues, not just material ingested. As with all tools, this method has certain limitations which must be borne in mind when interpreting its results. Firstly, specific environmental conditions must be met. This generally means an ecosystem with a limited and known number of sources of organic matter having different isotope ratios. Two sources with different isotope ratios are ideal; additional sources with other isotope ratios complicate interpretation. Secondly, the difference in isotope ratios of the two sources should be large compared with analytical variability. Thirdly, the ratios within each source should vary as little as possible.
